UPDATE: Britain sends military ship, plane to look for EgyptAir

Egyptian Civil Aviation Minister Sherif Fathi speaks at a press conference about the early morning crash of an EgyptAir flight from Paris to Cairo with 66 passengers and crew on board, in Cairo, Egypt.

Britain is sending a military ship and a plane to join the search for EgyptAir Flight 804, which Egyptian officials say has crashed into eastern Mediterranean Sea.

Defense Secretary Michael Fallon says he has dispatched Royal Navy support ship RFA Lyme Bay, which is in the Mediterranean, and a C-130 Hercules aircraft from Royal Air Force base Akrotiri in Cyprus to support the Egyptian-led effort. He says "we stand ready to offer further assistance" if needed.
